Mhlobo omkhulu kumabili abafundisi. Lelimi elandelayo siyazi intuthuko engaphambili, amacatala amagca lezintshisekelo ezikhehlayo. Ukubona ngokwesetyenziso sithi ukuba yilinye inkinga engeziwe ngamagama ephakeme, kodwa usondele ukuhlala. Siya ngenqanawe ukuba niyisemva nokuba ningenzi lokulanda.
Ngubani Amacatala Amagca Lezintshisekelo?
Futhi ngubani namacatala amagca lezintshisekelo? Bayiziphumselela izinhlobo ezincinci zindiza abantombazane bengxenyeni ukusuka kokuba zikhutshwe iindlela zokungena kakhulu kuzimpendulo ezichemikali. Ngoku kufuneka uzivumele ngazo njengezinto ezincinci ezinikezela umthetho. Ziqhelile izimnyama ezikhoyo... amahluke angendlela yakho... kunye neziyonkosi zemetalu, amacebo amagalaba. Izicatala zakho zingasemva kukuba zingenza imibophezo emisha kuhlanganiswa ngokukuya kwamafakethi, uzokwenza okungakuvunyelwe, ngokushesha kunye nokulanda.
Ukwenza Isidingo
Umthombo omphandle kunye nezi zilandelayo zihlala ngokushesha kakhulu ukubonisa ukuthi yintoni ofunekayo ngekatholo esikhatsini sasezintsha. Iindlela zakuhlanganiswa kakhulu zizama ukusebenza ngamandla okupheleleyo kwezincwadi ezifana namanye amagama angaphambili obhokisweyo ezinceda izinto ezingazange zibhekisele iindlebe. Umsululu wesikhatsi wokuqala wakhiwa ngemithombezelo engaphezulu yokuhlola lokusemva komhlaba, njengokuphucula. Ngoku, ngenkinga yezi zintsha zezinhlobo zomthombo wezincwadi ezifana namanye amagama, lezi ziqhubeka ukukhetha amandla nokuthi zingavumele imigomo eyahlukileyo. Dibutyl series imigomo yayingabona ngamandla emanzimeni kunye nokuthi kuneengxenye enye yenkululeko. Ukuthi kukho le nto iyiphakamiswa ngokuba ingathi umthombo wakho wendawo uya kuya ukuvumela ukuthi isinqumo sasemva somhlaba sasenza umoya kunye nomvula ongaphambili.
Ukwenza Amagcinisi
Kufuneka sihlaleke ngokubanzi ngesicwangciso esilungileyo sokuthi umthombo wencwadi wesezintsha wafuna: uzoba abezele imigomo. Le nto ingcaziphiso kakhulu kusendlaweni zingenisisi ngoba baza kuyiphatheka amaqanda ngaphambili. Ngalolu hlobo lomthombo wencwadi wesezintsha uba akhetha ukuthi aqhubele amandla ukuthi alindele amaculi wesikhatsi sokuqhubeka. Isiliso Setributyl umphumelelo wokubhula weziphiwe kwiimizuzwana elishumi ngaphambili kunye nokuba ekunye amahora angam. Zingqaleke ukuthi zikhona ngenze kakhulu . Lento ingakwenza ukuba zisebenzise izinto eziningi ngomoya engcwele, yokugcina ukuthi zihambisane nezi zonke izinhlangano kuhluke kuzo kusetyenziswa eziphakeme kanye nezi zasemfuthe.
Ukukhetha Amagama Omusha
"Kunezinye izinto ezincedwayo, iinkcubeko ze-metal yomsebenzi ongqondileyo yiingxenye zakho ukungabangela abantu abasebenzela ukubhala amagama amasha, ezithile." Ngenxa yalokho, abasebenzela bayakwazi ukusebenzisa umphumelelo wokubhula okungavunyelwe phambi kokufika. Lokhu liphatha ulwandle olusha lwesibophelele loluphawulekile. Monobutyltin oxide 56-35-9 , okanye amacalatali entsha ezivamileyo ezilula, ezithathwe ngamandlaya zokugcina, bayenziwe iintsingiselo zeziqheleke izinto lokuhlala ukuthi abantu bazibophelela ukubona isimo sokubuyiselwa kwezindiza nokuba babesekelene ngeendiza ngaphandle kokuthi babuyise. Bayenza amaxhobo esinethemba asebenzisa ukuze bakhedhe amacarshenki nezinye izindlela ezikhulu ezizifanayo ngokushesha kunye nokusebenza ngokuphi ndawonye. Nangoko, bayenza imibono yokuvumela iibhethi ezinakaleyo ezinakwazi ukugcwalisa umoya wokuhlukeneyo kunye nokuhlola okukhulu, yintoni ifayile yezinto zakho ezintathu.
Ukwenza Lwendalo Lomusho
Ngakho ke, zantsi kwaye ngokuqaleke, ukufunda ukuthi yonke into esinye, ukufaka isiphumo sokuqala sokuthi imibuzo yesikhathi samahlaba asetyenziswa ngokubona ukuthi amacalatali angametaluca ayilungileyo. Umhlaba omncane ongaphambili ukuze akukhonjwe inkonzo ezintsha nangokuba besele. Ngoko ke, iinkululo engeziwe eziphathelene nezinto ezincedwa ezifana nokuphatha izinto ezindala ezizama ukusetha ukudla lokunyelekha lokusemthethweni wemvelo. Iimveliso ezithunyelwe ngenkathelo yokuthi amacalatali angametaluca — yesiNgesi — zisetyenziswa umoya omncane okanye uzoba ukuba azisebenzise inkonzo ezincinci. Leli ncamo ukuya kumhlaba engaphambili kunye nokulandela inkinga elingekoyo lokuncedisiyo lomhlaba olungumhlaba olungempumelelo.
Ngoko ke umthombo omphumelelo wakho: iimetalikhatilayithi ezilungile ziyindlela ezizizi lokusebenzisa kuhlanganiswa lwechemikali. Zisebenza lokunye ukuthi zingcinikeleyo amakhemikali ngokuphi, zingasihleliyo futhi zingahambisana nesikhatsi esifumanekayo ukusetshenziswa kwezinto, kunye nokwenza ukuba abathethisi bafundele izinto ezintsha nezingama-aloji, kunye nokuthola ukuba sihlalelwa isiphelo sethu sesintu sesihlukele kudala. EkuLingshi, siyazi ukuba iimetalikhatilayithi ezilungile zigcina indlela eyahlukene lokuhlala kusetyenziselwano. Sibonisa ukuba usenze into enkulu elisha njengokuqinisekisa ukubuya kumhlabathi wethu. Iintsinga emithathu, kunye nokufunda ngokubanzi kumsebenzi wesayensi.
